[Bug]: Undefined symbol to `testing::internal::PrintTo` for `std::u8string` #4528

Closed HenryAWE closed 4 months ago

Describe the issue

If I used the library provided by the system package manager like pacman of Arch Linux, I will get a link error complaining about the PrintTo for std::u8string is undefined. But if I use the FetchContent to build the same version (v1.14.0) of GoogleTest for my project, this error disappears.

Compiled with -Dpapilio_build_unit_test=1

What version of GoogleTest are you using?

v1.14.0

What compiler and version are you using?

I didn't try this and we don't support pre-compiled libraries from package managers. However, I would guess that the problem is related to C++20. u8string is only available in C++20, and I bet the package you are linking against isn't built with C++20 support.
